In the above example, the elif conditions are applied after the if condition. Python will evalute the if condition and if it evaluates to False then it will evalute the elif blocks and execute the elif block whose expression evaluates to True. If multiple elif conditions become True, then ...
If user enters-2, the conditionnumber > 0evaluates toFalse. Therefore, the body ofifis skipped from execution. Indentation in Python Python uses indentation to define a block of code, such as the body of anifstatement. For example, x =1total =0# start of the if statementifx !=0: tot...
elif … sequence is a substitute for the switch or case statements found in other languages.可以有多个elif语句，关键词elif是else if的缩简写，用于缩减语句长度。if … elif … elif … 与其他语言的switch或case语句的作用相近。if condition_1:statement_block_1 elif condition_2:statement_block_2 else...
‘If statement in Python is an eminent conditional loop statement that can be described as an entry-level conditional loop, where the condition is defined initially before executing the code. Python does not contain an incremental factor in the syntax. It is used for printing or performing a pa...
if not Condition: # Statement block Here’s an example of using the logical operator named Not in Python user_age = int(input("Enter your age: ")) if not user_age > 18: print(f"You cannot donate blood, please come back after {18-user_age} years") ...
ifcondition:code_block 1. 2. 其中,condition是一个表达式,用于判断条件的真假。如果condition为真,则执行code_block中的代码;否则,跳过code_block,继续执行后续的代码。 if语句中的多条代码执行 当我们需要在条件满足时执行多条代码时,可以使用缩进来表示代码块。在Python中,缩进是非常重要的,它决定了哪些代码属于...
Elif Conditional Statement in Python Elif is a rather unique term as other programming languages don’t use it. Other programming languages use"else if "to put up one more condition. While Python combines"else and if "and makes it an"elif "conditional statement. The usage of the"elif "stat...
If `condition` is a string (e.g. ‘${rc} < 10’), it is evaluated as a Python expression using the built-in ‘eval’ function and the keyword status is decided based on the result. If a non-string item is given, the status is got directly from its truth value. ...

For example, if we want to check if a number is greater than 10, we can write the following "if" statement: if number > 10: # code to be executed if the condition is true print("The number is greater than 10.") If the condition is true, the code inside the block will be execu...
